FOI reference: FOI-2025-2966

You asked

I would like to use the FOI to inquire whether data exists on the number of non-standard housing in the UK.

Included in this, I'd ideally like the percentage of UK households that are classified as non-standard or non-traditional.

We said

Thank you for your request.  

We do not use "non-standard" or "non-traditional" in the classifications that we use for housing (buildings and dwellings that people live in) or for households (the people that live in the housing). As your request references both housing and households, we have provided some information relating to both, which may help answer your question.

It is important to note that housing is a devolved power and so statistics are not always available at UK level.  

For housing:  

For households:
